We are using G2 4K E without any internet connection during product life. We would like to avoid the time consuming step of setting date and time of each headset manually...
Thank you in advance for your suggestions.
Dear developer, it is not supported to set date and time through ADB currently. Sorry for the inconvenience.
Not sure if this helps but you can set the time zone.
adb shell setprop persist.sys.timezone "America/Chicago"
